“…It is possible to observe from the results that the amount of austenite volume fraction on the specimen A is higher than on the specimen B. Figure 15 illustrates the principals fiber and components textures orientations in the Euler space ( 2 = 45º) [15]. …”

“…At both HAZ1-2 and FHAZ, Figures 9(d) and 10(b,d), there is an intense intragranular austenite precipitation in ferrite caused by heating at intermediary temperatures during the second thermal cycle. These precipitates also have Widmansttäten morphology, and are known as secondary austenite in literature [15,16]. This type of austenite can nucleate intragranularly, directly at the ferrite grain boundary (Fig.…”

“…It is possible to observe that in the central zone of the weld (FHAZ), where the cooling takes more time (compared to HAZ1 and HAZ2) there is an increase on the amount of austenite and that at the HAZ1-2 there is an increase on ferrite. This will eventually favor the precipitation of the  phase in subsequent heating, as it occurs, for example, in multi passes welding [15]. The HAZ presented two regions: one of high temperature, which has small and dispersed austenite grains and a second low temperature region with the remained austenite from the base metal.…”

“…The amount and morphology of the ferrite affect the properties of the weld joints as cracking susceptibility, corrosion resistance and low temperature fracture toughness. Furthermore, it was suggested that some of these properties are related to the crystallographic relationship between  and  [14][15][16].…”

“…According to Badji et al [15], limited information is available in the literature on the link between texture, microstructure and anisotropic properties of duplex stainless steel after arc welding. Understanding the development of crystallographic textures and microstructures in these welds can be very useful to control their final properties especially when, for instance, a post-weld annealing treatment is to be carried on.…”

This paper describes the electron backscatter diffraction (EBSD) technique used to characterize the microstructure (especially the morphology and constitution) of the base metal (BM), the heat-affected zone (HAZ) and the fusion zone (FZ) on a lean duplex stainless steel (LDX). This technique provides advantages due to its simplicity of use and greater depth of information, thereby increasing the amount of information obtained by traditional characterization techniques such as optical microscopy (OM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The use of EBSD together with orientation imaging microscopy (OIM) as a tool to understand phase transformation paths and ferrite-austenite variant selection was discussed. Vickers microhardness measurements were performed and no significance difference between the different zones was found. Orientation distribution function (ODF) results show that there are no significant changes on the crystallographic texture of the samples after welding. The advantages of using SEM together with EBSD for microstructure analyzing and texture development were also discussed.

The metallurgical behaviour by Duplex stainless steels welding is affected by reducing the austenite proportion in weld and in the area adjacent to the fusion line of the molten metal bath and also by the precipitation of nitrides Cr2N, carbides M23C6 and intermetallic phases, σ, χ, Laves. The modalities for obtaining a quantitative ratio of the two phases (Austenite/Ferrite) close to that of the base metal (∼50 % Austenite and 50 % Ferrite) aims to adjust the chemical composition of the weld by selecting a filler material with a higher nickel content (the element which beside nitrogen promotes the austenite formation), the heat cycle control of the welding process and the application of a post‐welding solution treatment. The present paper explores the effect of such heat treatment on balance restoring between austenite and ferrite and the reduction of the alloying elements segregation phenomena. By optical and scanning electron microscopy examinations and also X‐ray diffraction analyses the microstructural changes induced by the applied treatment are highlighted and by impact toughness and static tensile tests is demonstrated the positive effect of the heat treatment onto the ensuring of the welded joints quality.
